The One Bottle Water Relay: How Jiangsu Built a Decade-Long Cooling Network for Outdoor Workers

Across the industrial heartlands of eastern China, a quiet but formidable civic experiment has matured into something far more consequential than a seasonal charity drive. The "One Bottle Water Relay," launched in 2017 by Jiangsu Swire Coca-Cola, began as a modest gesture of gratitude toward sanitation workers and traffic police who endure punishing summer heat.

Ten years later, it has evolved into a distributed cooling infrastructure that spans historic districts, airport taxi ranks, corporate retail chains, and neighborhood restaurants. The program's tenth-anniversary figures — 75,852 bottles distributed this year alone — tell only part of the story, because the deeper transformation lies in its architecture of participation rather than its volume of output.

What distinguishes this initiative is its deliberate migration from one-way donation toward shared stewardship. Outdoor workers no longer wait for volunteers to hand them water; they simply take it from refrigerators and pick-up points positioned along the routes they already travel.

This subtle inversion — from recipient to autonomous participant — reframes public welfare as an ambient civic utility rather than an episodic act of pity. The organizers describe it as "public welfare for all," a phrase that captures how government bodies, Youth League committees, media outlets, unions, and private enterprises have fused into a single cooling network.

The program's ten-year arc also mirrors a broader shift in how Chinese cities conceptualize labor dignity. By expanding its beneficiary base from sanitation staff and police to couriers, delivery riders, and gig-economy workers, the relay acknowledges that informal and platform-based labor now constitutes a permanent, visible stratum of urban life.

Understanding this evolution requires examining its logistics, its coalition structure, and the replicable model it offers to other heat-stressed regions worldwide.

TL;DR Jiangsu's "One Bottle Water Relay," founded in 2017 by Jiangsu Swire Coca-Cola, has completed ten years of operation and now distributes drinking water through a decentralized cooling network rather than isolated handouts. This year's campaign delivered 75,852 bottles via ten "Happy Water Carrier" stations, community refrigerators, and commercial pick-up points across cities including Nanjing and Changzhou. The program has expanded its beneficiary base from sanitation workers and traffic police to couriers, delivery riders, and ride-hailing drivers, while assembling a coalition of government, media, unions, and private enterprises. It represents a shift from charitable donation to shared civic participation, positioning water access as ambient infrastructure for outdoor labor.

The Origins and Ten-Year Evolution of the Water Relay

The program's genesis in 2017 was unremarkable by design. Jiangsu Swire Coca-Cola simply wanted to place drinking water in the hands of people whose jobs made heat exposure unavoidable. Sanitation staff begin sweeping before dawn; traffic police stand at intersections through the hottest hours.

The initial intervention targeted these two groups almost exclusively, treating water as a direct gift with no expectation of reciprocity or continuation.

Ten years of iteration changed that logic entirely. Organizers gradually recognized that episodic donation creates dependency on volunteer schedules, whereas embedded access creates resilience. The relay therefore began installing fixed refrigerators and pick-up points at locations workers already frequented, converting charity into routine.

This year's campaign distributed 75,852 bottles, a figure that reflects both scale and the efficiency of decentralized distribution.

From Single Donation to Distributed Infrastructure

The decisive conceptual leap was spatial rather than financial. Instead of organizing one-off distribution events, the program mapped the daily trajectories of outdoor workers and planted water access along those paths. A courier passing a community refrigerator in a historic district can hydrate without breaking stride or requesting assistance. This design respects both the worker's time and their dignity.

Organizers explicitly frame the shift as movement "from one-way donations to shared participation." That language matters because it repositions the worker as an agent rather than a beneficiary. The infrastructure becomes ambient — present, predictable, and unremarkable — which is precisely what makes it sustainable across a decade of summers.

The Role of Corporate and Community Anchors

Su Shi Group opened 560 outlets to serve as distribution nodes, an extraordinary commitment that transformed retail footprint into civic infrastructure. Neighborhood restaurants including Hengji, Baoji, and Liji contributed space or refrigerators, embedding the network into the texture of everyday commercial life. These anchors provide permanence that temporary stations cannot match.

Commercial participation also solves a logistical problem that plagues traditional charity: refrigeration. Bottled water left in open heat becomes undrinkable within hours. By leveraging existing cold-chain capacity in convenience stores and restaurants, the program guarantees that every bottle dispensed is genuinely refreshing rather than merely available.

Mapping the Cooling Network Across Jiangsu Cities

Geography is the program's silent organizing principle. Water access points cluster where outdoor labor concentrates: historic tourist districts, transport hubs, municipal construction zones, and dense residential neighborhoods. The network's spread across multiple Jiangsu cities reflects deliberate coordination rather than organic scatter, with organizers selecting sites based on worker density and route overlap.

Ten "Happy Water Carrier" stations operated across ten days and ten locations, functioning as high-visibility anchors for the broader network. Meanwhile, permanent community refrigerators and commercial pick-up points provide the quiet, continuous backbone. This dual structure — temporary spectacle plus permanent utility — balances media attention with durable service delivery.

Historic Districts and Tourist Corridors

Laomendong and Xinanli, two of Nanjing's most visited historic districts, host cooling points that serve both tourists and the workers who maintain those spaces. Sanitation staff, security personnel, and delivery riders converge on these areas in high numbers during summer months. Placing water there addresses a genuine density problem rather than a symbolic one.

The D9 area and a youth service station at the taxi holding area of Lukou Airport extend the network into transport infrastructure. Ride-hailing and taxi drivers waiting in holding areas face prolonged heat exposure with limited access to facilities. A dedicated station at the airport acknowledges that their labor continues even while they wait.

Community Sites and Neighborhood Integration

Changzhou's community sites demonstrate how the program embeds itself in residential life rather than treating outdoor workers as transient visitors. Neighborhood refrigerators sit alongside restaurants and shops, making water access indistinguishable from any other routine errand. This integration reduces stigma and increases usage frequency.

Union service stations and youth volunteer service stations joined the cooling network, adding institutional permanence. These are not pop-up tents but existing facilities with staff, schedules, and accountability. Their participation converts scattered goodwill into a coordinated system capable of surviving beyond any single summer campaign.

The Coalition Architecture Behind Public Welfare for All

No single actor could sustain a cooling network of this scale. The program's durability rests on a coalition that spans government, social groups, media, corporations, and the general public. Each participant contributes a distinct capability: legitimacy, labor, amplification, refrigeration, or daily usage. The result is a system where no single point of failure can collapse the whole.

A city Youth League committee provides institutional backing and volunteer coordination. Union service stations contribute existing facilities and staff. Media outlets Yangzi Evening News and Ziniu News followed the ten-day, ten-station activity, converting local service into publicly visible civic narrative. This visibility attracts further participation, creating a self-reinforcing cycle.

Government, Media, and Corporate Roles

Government involvement supplies the legitimacy that allows the program to operate across multiple jurisdictions without friction. Youth League committees and union stations bring organizational capacity that private actors cannot replicate. Their participation signals that cooling access is a public responsibility rather than a corporate marketing exercise.

Media coverage performs a dual function: it documents the program and recruits new participants. When Yangzi Evening News and Ziniu News report on the ten-day activity, they transform a local logistics operation into a replicable civic template. Other cities and organizations can observe, adapt, and implement similar networks.

Restaurants, Neighborhoods, and Everyday Participation

Restaurants such as Hengji, Baoji, and Liji contributed space or refrigerators, demonstrating that participation does not require large capital. A single refrigerator in a neighborhood eatery becomes a cooling node serving dozens of workers daily. This low barrier to entry explains the network's rapid geographic spread.

Local enterprises and institutions joined alongside individuals, creating a layered participation model. Some contribute infrastructure, others contribute visibility, and still others simply use the service as intended. The organizers describe this as "public welfare for all," a formulation that deliberately blurs the line between donor and beneficiary.

Expanding the Definition of Outdoor Labor

The program's beneficiary list has grown in lockstep with China's changing labor landscape. In 2017, outdoor work meant sanitation and traffic management. By 2026, it encompasses couriers, food delivery riders, taxi drivers, ride-hailing drivers, and construction workers in tunnels and municipal pipe networks. Each category faces distinct heat exposure profiles.

Construction workers in tunnels and pipe networks confront a paradox: they labor underground yet endure extreme heat because ventilation is limited and machinery generates additional warmth. Couriers and delivery riders face continuous exposure with minimal shelter and tight delivery windows that discourage rest. The program's expansion acknowledges these differentiated vulnerabilities.

Gig Economy Workers and Heat Vulnerability

Platform-based delivery riders operate under algorithmic pressure that penalizes pauses. A rider who stops to seek water risks falling behind on quotas or losing incentive bonuses. Placing water directly along delivery routes removes that friction, allowing hydration without economic penalty. This design detail reveals sophisticated understanding of gig labor conditions.

Taxi and ride-hailing drivers waiting at holding areas such as Lukou Airport face a different problem: they are stationary but exposed, often for hours. A dedicated youth service station at the airport holding area addresses this specific bottleneck. The intervention is small but precisely targeted at a known pain point.

Sanitation Workers and Traffic Police as Founding Beneficiaries

Sanitation staff and traffic police remain central even as the program broadens. Their work schedules — pre-dawn starts, fixed posts through peak heat — make them the most predictable beneficiaries. The program's original focus on these groups established credibility that later expansions could build upon.

Ten years of continuous service to these founding beneficiaries demonstrates reliability. Workers who have received water every summer for a decade trust the network. That trust is the program's most valuable asset, enabling it to extend services to newer labor categories without suspicion or resistance.

Measuring Impact and the Road Beyond Year Ten

Quantifying the program's impact requires more than counting bottles. The 75,852 figure distributed this year represents hydration events, each occurring at a moment of genuine need. But the deeper metric is structural: a network of refrigerators, stations, and commercial nodes that persists between campaigns and requires minimal activation energy each summer.

Organizers state the program will continue beyond its tenth year, signaling that this is not a commemorative exercise but an ongoing commitment. The transition from project to institution is the most significant milestone. Projects end when funding or attention wanes; institutions persist because they are embedded in routine operations of multiple organizations.

From Charity to Civic Infrastructure

The program's trajectory illustrates a broader principle: effective public welfare eventually becomes invisible infrastructure. When water access is as unremarkable as a streetlight or a bus stop, the intervention has succeeded. Workers no longer think of it as charity; they simply use it as part of their environment.

This invisibility is the goal, not a failure of visibility. Programs that require constant promotion to survive are fragile. Programs that become ambient utilities — expected, relied upon, unremarked — achieve durability. The One Bottle Water Relay appears to have crossed that threshold in Jiangsu.

Replicability and Lessons for Other Regions

The model's components are not Jiangsu-specific. Any heat-stressed region with dense outdoor labor, existing commercial refrigeration capacity, and willing institutional partners could adapt the template. The critical ingredients are route-aligned placement, low-barrier participation, and multi-stakeholder coordination.

What cannot be easily replicated is the decade of accumulated trust. Workers use the network because they have used it for years without interruption. Building that trust requires sustained commitment across multiple summers, through organizational changes and shifting personnel. The program's real lesson is patience.

Why This Model Matters for Global Heat Adaptation

Heat waves are intensifying across every inhabited continent, and outdoor labor remains structurally indispensable to urban function. Cities worldwide face the same question Jiangsu confronted in 2017: how do you protect workers who cannot retreat indoors? The One Bottle Water Relay offers a partial but instructive answer grounded in a decade of practice.

The model's genius lies in its refusal to centralize. Rather than building dedicated cooling centers that workers must detour to reach, it distributes access along existing routes. This reduces the behavioral cost of hydration to nearly zero, which is essential when workers face time pressure and productivity penalties for pausing.

Equally important is the coalition structure. By enrolling commercial outlets, media, unions, and government bodies, the program distributes both cost and responsibility. No single budget line bears the full burden, and no single organizational failure can halt operations. This redundancy is a feature, not an inefficiency.

For regions considering similar interventions, the Jiangsu experience suggests three priorities: map worker routes before placing infrastructure, recruit low-barrier participants such as restaurants and shops, and commit for years rather than seasons. Trust accumulates slowly and cannot be shortcut through promotional campaigns or one-time funding injections.

The program's tenth anniversary is therefore not a conclusion but a proof of concept. It demonstrates that public welfare can evolve from episodic charity into ambient civic infrastructure, provided organizers resist the temptation to centralize and instead cultivate distributed participation. That lesson travels well beyond Jiangsu's borders.
